摘要：

Targeting at the problems of fuzzy evaluation system and neglect of triggering factors such as rainfall in the susceptibility and hazard assessment of debris flows，a study was conducted in the Fushun City based on analysis of the development and distribution patterns of debris flow disasters，the analytic hierarchy process method was utilized to assess the susceptibility and disasters of debris flow，using hydrological response units as evaluation units. The assessment accuracy is evaluated by incorporating existing debris flow disaster points. The results show that among the 42 existing debris flow disaster points，36 are located in the high and extremely high susceptibility areas（accounting for 85. 71%），and 33 are located in the high and extremely high hazard areas （accounting for 78. 57%）. This indicates that the susceptibility and hazard assessment results are reliable and consistent with the current development situation of debris flow disasters in Fushun City. © 2024 Northeast University.
